Involute type centrifugal water segregator

Abstract

The involute type centrifugal water segregator comprises a shell and a spiral blade, an air inlet cavity and a separation cavity are formed in the shell, the axial direction of the air inlet cavity is in the front-back direction, the cross section, perpendicular to the axial direction, of the air inlet cavity is circular, and the side wall of the air inlet cavity is in smooth transition from back to front; the spiral blade is arranged in the air inlet cavity, the separation cavity extends in the front-back direction, a rear end opening of the separation cavity is connected with the air inlet cavity, the cross section, perpendicular to the front-back direction, of any position of the separation cavity is in an involute shape, and a blocking wall is formed between the starting point 0-degree position and the ending point 360-degree position of the involute. A water drainage hole is formed in the blocking wall, the shell is provided with a front end wall arranged at the front end of the separation cavity, and an air outlet is formed in the front end wall. The involute type centrifugal water separator is good in gas-water separation effect, capable of solving the problems that water separation is not thorough and water separation efficiency is low, simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the field of water separators, in particular to an involute centrifugal water separator. Background technique [0002] The fuel cell will continuously generate liquid water during operation, and under the action of air flow, the liquid water will flow inside the fuel cell system along with the pipeline. For the anode system, too much water will cause the proton exchange membrane to be flooded and block the hydrogen-oxygen reaction channel; for the cathode system, if a large amount of liquid water is entrained in the gas, it is used to recover energy under the action of high-speed airflow Turbines are subject to impact corrosion and kinetic energy impact from water droplets. Therefore, an efficient water separator is very necessary. [0003] At present, the common water separators are labyrinth baffle water separators and centrifugal water separators. Most of the labyrinth baffle-type water separators have a labyrinth flow ch...

AI Technical Summary

Problems solved by technology

The experimental results show that this kind of water separator has a good performance at medium and low flow rates, but when the air velocity is high, water droplets will always rotate along the inner wall of the water separator without settling and converging; At the same time, under the action of high-speed airflow, the liquid water that has accumulated at the bottom of the inner cavity will be washed away and redistributed in the air, resulting in incomplete water separation and reduced water separation efficiency
